What is the total fetal dose limit for a declared pregnancy?

• A. 0.5 mSv
• B. 5 mSv
• C. 1 mSv
• D. 10 mSv

Answer: (B)

The main idea is that there is a cumulative dose limit for the fetus when a pregnancy is declared. The fetus should not receive more than five millisieverts from all occupational radiation sources during the entire pregnancy. This limit helps protect fetal development while still allowing the worker to continue essential duties with appropriate controls. In practice, you meet this by managing workload, reducing time near sources, maximizing distance, and using shielding, along with monitoring fetal exposure if available. If projected exposure could reach or exceed five millisieverts, duties should be reassigned or additional shielding and protection strategies implemented to stay within the limit. The other numbers don’t reflect this overall pregnancy limit; they would either underrepresent or overstate the protective guideline for the fetal dose.
